Small concrete pad issue

In our yard when we bought our home, there was a concrete pad in one corner 8 X 10. I had recently demolished and removed a poorly built, rotted and bug infested 8 X 12 shed in another part of our yard. That shed was built over top of dirt and sitting on top of paver blocks. We are purchasing a new fully built 8 X 12 shed to have delivered, but the area where we want it is where the 8 X 10 slab is. Any reccommendations on what to do to make this work as far as making this area bigger for the shed? Im thinking hiring a company to come out and they can extend it with more concrete? Then again, not much more is needed to enlarge the area. So im imagining anyone would say its not worth there time etc.

This would be expensive, due to the minimums... will take the same amt of time due to set up time. You might consider doing this yourself with a friend who has some experience. Add a 2ft strip on the end. Use simple form, 4" depth, sack cement from Home Depot. If I were going to do it, the minimum would be $400=, It takes the same amt of time to pick up 2 pallets of concrete mix and 20 bags, same amt of time to finish as a full slab, not as much in form or grade, but the trip charges runs this up. i would bid over the phone, not worth the trip to look at, that would run the price up another $100 for a trip bid. By the way, pick up 5 extra bags of what you think it will take, you do not want to run after more during the poor. You will need a friend, this will be tiring if your not used to this type of work.
Another option, add on with pavers, doesnt matter if it matches, it is a shed. Put Gravel sand 4" bed under where the pavers go and compact, once again a guy with a little experience will help, you do the chasing and save that cost... Could be done in a couple of hours. You just want something other than dirt under the shed.
